Answer:
0.066m
Explanation:
use the formula
velocity= frequency × wave length
344m/s = 5200Hz× wavelength
wavelength = 344m/s/5200Hz
wavelength = 0.066m(to 2 sig fig)
When the resultant force is not equal to zero termed an unbalanced force. By procedures 4 and 5 students observe an unbalanced upward force on Box 1. Hence option 1 is right for the problem.
<h3>What is an unbalanced force?</h3>
The forces operating on a body are known as unbalanced forces when the resulting force exerted on it is not equal to zero.
Unbalanced forces acting on the body, causing it to modify its state of motion. To further grasp the nature of imbalanced forces.
<h3 />
The following reasons by which we can understand the unbalanced force caused by the box.
Due to these two reasons, books will move up.
By adding another mass to box 2. The box becomes lighter. As the box becomes lighter the gravity force acting on the box will be less due to which the box easily can move up.
By removing the two masses from box 1. Due to which other become heavier other becomes heavier pulling it down causing box 1 one to go up.
Hence by procedures 4 and 5 students observe an unbalanced upward force on Box 1. Hence option 1 is right for the problem.

Answer:
He could use magnets to lift heavy things and also move things like a train
Explanation:
i had the same question
Cases A and B are all correct.
In Case C, the GPE is incorrect.
(But then, the power and HP have been correctly calculated
from the incorrect value of GPE, so we can't gig you too bad.)
